I take birth control pills to help my acne so i don't take it daily or properly (though i try). I had unprotected sex during the last few days of my my period around the time when i was suppose to take the inactive pills. My period started about two weeks early. I have dark brown spotting, more like a mini-period. There is also light cramps, headaches and diarrheas. Are these symptoms of having sex during one's period? am i okay? Or are they signs of other problems?
